ETA

Heating solutions for local and district heating

With the ETA PVM, excess electricity from the photovoltaic system is directly converted into usable heat and efficiently integrated into the heating system. This will increase your self-consumption, relieve the strain on your heating system and allow you to use self-generated energy.

The buffer storage tank – the heart of heat distribution
Heat is stored here, which in turn can be accessed at any time if more energy is needed. So the buffer storage tank evens out peak and reduced loads and thus ensures a uniform and more efficient operation of the heating system and also a longer lifetime of the boiler. A well-adjusted stratified buffer significantly enhances comfort as well.

Efficient heat storage using solar power
As a central element in the heating system, the stratified buffer storage tank plays a key role: In addition to absorbing energy from biomass, it also absorbs the heat generated by the solar thermal system and makes it available as needed – for hot water preparation as well as for heating support. This enables intelligent utilisation of energy surpluses, balances load fluctuations, and protects the boiler. This ensures not only consistent and economical operation but also significantly enhances living comfort.

Always hygienic, always fresh
The fresh water module ensures that the buffer storage tank is used even more efficiently. When hot water is needed in the house, the fresh water module kicks in: using the instantaneous water heater principle, it heats fresh cold water as needed and hygienically – exactly when it is required. For maximum comfort and consistently clean hot water.

Harnessing the power of the sun:
The stratification of solar heat in the buffer tank is made possible by the stratified charging module. This ensures optimal use of solar thermal energy for hot water production and heating support. For example in the morning when the sun is weak, the module supplies the lower half of the buffer. Once the sun is sufficiently strong to heat the upper, warmer buffer strata, the system switches to the upper half.

Clean separation for various systems
Whenever heating circuits need to be separated, the ETA system separation module is used – for example, to separate residential heating from frost-protected areas such as workshops, stables or open areas. Separation also protects against damage in old underfloor heating systems or stable heating systems that introduce oxygen or pollutants into the system. The media are reliably separated from each other using a plate heat exchanger – similar to solar thermal systems.

The ETA heating circuit module for 2 mixing heating circuits saves a lot of time and money during installation, because there is no need to lay sensor lines, pump and mixing cables. All components are connected to the already integrated control system.

Well-thought-out solutions for district and local heating
The heat transfer station from ETA is the professional solution for private and commercial heating networks.  It is not only suitable for new construction, but is also particularly well-suited for the renovation of buildings that do not have their own boiler.

The first heating circuit and hot water charging are integrated into the module and operate with only one highly efficient heating pump. In addition, the ETA module concept and the ETA touch control system also allow other solutions, so that individual systems can be designed.

Well-designed solutions for district and local heating
ETA transfer stations are available in various power ratings. These compact heat transfer stations are used for direct connection to district and local heating plants for indirect operation.

All those important components needed for a district heating operator are already pre-installed and pre-wired. Connection to a household system can also be done easily and individually. The ETA control is already integrated, and can be optionally expanded as required.
